There was an air leak and I thought this would be a quick and easy fix. The worst. Mistake. Is always. It was a nightmare to put all that slime in the tire. Then about a week later I noticed it was low again. And today I literally blew out a tire. The mechanic said the patch had accumulated unevenly in the tire and was causing this. Now I spend 100β¬ on a new tire. Even though I followed the instructions and drove slowly after filling the tire with mud, something went wrong. I would just go to a pro and do a proper patch.
